1 'Claim.

My present invention relates to an improved knockdown chair of the typecomprising a minimum of parts so arranged that the assembly ordisassembly may be accomplished in a very short time, and at the sametime, the chair or table made according to my invention will be whenlocked in position strong and durable. Due to the simplicity of theparts, the chair or table may be manufactured at low cost, and will filla need in collapsible furniture for indoor or outdoor use.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised but it will be understood that various changes andalterations may be made in the exemplified structure within the scope ofthe appended claim.

In the drawings:

Figure 1 is a side elevational view of the assembled chair according tomy invention.

Figure 2 is a front elevational view thereof.

Figure 3 is a top plan view of the chair.

Figure 4 is an enlarged detail view of the front locking dowel for theseat; and Figure 5 is a sectional view thereof at line 5-5 of Figure 4.

Figures 6, 7, 8, 9, and are plan views of the various elements of thechair.

Figure 11 is an end elevational view of the structure of my invention asembodied in a knockdown table.

Figure 12 is a side elevational view thereof.

Figure 13 is a perspective View of the dowel and dovetail slot lockingmeans for the table top.

Figure 14 is a bottom plan view of the assembled table.

Figure 15 is a plan view of the side piece.

Figure 16 is a plan View of the leg elements.

Figure 17 is a partial bottom plan view of the table top showing thelocking slot; and

Figure 18 is a Vertical sectional View of the table top through the slotof Figure 17.

Referring now to the drawings wherein like characters indicate likeparts I have illustrated the present embodiment of the structure of myinvention as comprising the sides 2 having legs 4 and 6 with the backsupports 8, and provided with vertical notches 12 over the front legs 4,horizontal slots [4 over the rear legs 6, and vertical slots 16 at theupper ends of the back supports 8.

A front brace member 18 is formed with notches 20 for co-action with thenotches l2, and the upper edge of the brace is dovetailed as at 22.

The seat 24 is provided with rear notches 2B for co-action with thenotches it of the sides and 2 the slot 23 near the rear edge of the seatis locked as hereinafter stated, while the dowel 36 under the front partof the seat engages the dovetail 22 of the brace.

The T-back 32 is formed with notches 34 in the under edge of the crossmember for co-action with the notches it of the back supports 8, and thebase 35 is fitted for insertion through the slot 28 of the seat. Avertical slot in the base of the back as at 38 is positioned at a pointin the base 36 so that it will be below the seat when the base isinserted through the slot 23, and the wedge 48 is passed through theslot 38 to frictionally engage the under side of the seat and thusretain the wedge in driven position,

All of the five parts hereinbefore described may be of plywood or othersuitable material, and may be ornamented or dadoed as desired, and itwill be apparent that when the parts are assembled as stated and asshown in the drawings, the chair parts will be locked securely inposition. No tools are required either in the assembly or disassembly,as any suitable object may be employed to drive home the wedge.

A further exemplification of the structure of my invention is set forthin Figures 11 through 19 of the drawings wherein the invention isembodied in a knockdown table.

This embodiment comprises the legs 42 and 44 connected by member 46 andhaving upper notches 48, the dowels 59 in the upper edge of theconnecter. The sides 52 are notched at 54 for co-action with the notches48 and dowels 56 are positioned central of the upper edge of these sidemembers,

The table top 58 is provided with dovetailed slots 6|] drilled at 52 forthe entrance of the dowels, and when the legs and sides have beenassembled and interlocked, the top is placed thereon with the drilledopenings to the slots aligned with the dowels, and then a slightmovement of the top will seat the dowels in the dovetailed slots.Disassembly follows a reverse procedure.

From the above description of the construction and manner of assembly itwill be apparent that the chair and table incorporating the structure ofmy invention may be assembled with facility and ease, and thedisassembled elements may be packed in a relatively small package forcarrying or storage.

No nails, screws, glue or other matter is required other than theinterlocking slots and notches of the various elements, and in the caseof the chair, the wedge is the key to the locking 3 of the assembly,while in the case of the table, the dowels and the dovetailed slotsprovide the locking means.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

A knockdown chair comprising notched leg and back support sections, anotched seat engaging the lower portion of th back support sections andresting on the top of the leg sections, a front brace interlocked withthe leg sections and having an upper dovetailed notch, a fan shapeddowel on the seat engaging the latter notch, a back having notchesengaging the back support sections and a lower tongue extending throughthe rear of the seat and formed with a slot therethrough, and a wedgethrough th slot engaging the under side of the seat and comprising thekey to the assembled chair.
